Problem Description

In Redux, the calculation of the mergedProps depends on determining whether ownProps have changed. If ownProps change while shouldComponentUpdate is blocking the recalculation of mergedProps, a subsequent state update or propagation of seemingly unchanged ownProps (which appear the same as the last ownProps but differ from the ownProps before the blocking period) may result in incorrect mergedProps calculation. This issue arises because changes in ownProps during the blocking period are not taken into account.

Solution

This PR introduces a mechanism to detect changes in ownProps that occur while shouldComponentUpdate optimization is in effect. If such changes are detected during this blocking period, the next permitted component update will trigger a recalculation of mergedProps considering the updated ownProps.

@shirlynwix I split the test into 3 smaller tests in hope to make it more clear. Let me know what you think.
